Samenvatting:
Alkaline etching is frequently used in the processing of silicon into solar cells. High temperatures (above 100°C) and concentrations (> 10 M) of typically NaOH or KOH solutions are used for the fast removal of saw-damage for the wafers as-cut from the ingot. At low concentrations (less than 10 M)
and temperatures (< 100°C) these solutions are used particularly on monocrystalline (100) oriented silicon wafers for the formation pyramidal etch structures having excellent anti-reflective properties.
